Dynamically enabling an interactive element within a non-interactive view of a screen sharing session

ABSTRACT

A non-interactive screen sharing session executing within a computing device can be identified. The device can be communicatively linked to different computing devices of the screen sharing session. The contents of the remote screen buffer can be analyzed to determine a graphical representation of a Uniform Resource Locator (URL) within the contents prior to presenting the contents of the buffer within the device. A visible information item can be extracted and a non-visible reference can be established from the representation. An area surrounding the representation including a position and dimensions of the representation within the contents can be determined. The representation of the URL can be replaced with an interactive element in real-time. The element can include the visible and non-visible reference. The contents of the buffer can be presented within an interface associated with the session of the device, responsive to the replacing.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 14/185,344, filed Feb. 20, 2014 (pending), which is incorporated herein in its entirety.

BACKGROUND

The present invention relates to the field of collaborative computing and, more particularly, to dynamically enabling an interactive element within a non-interactive view of a screen sharing session.

Applications such as instant messaging applications and productivity applications can allow users to easily collaborate to perform important tasks. Many times, these applications include collaborative features such as screen sharing and Web conferencing. These features can offer a high degree of collaboration when users interact with other users via a shared screen. Common features of these applications often include a non-interactive mode which permits participants to observe a shared screen without granting access to the shared screen. For example, slideshows are frequently used within Web conferences to quickly communicate complex ideas with a large group of participants. The functionality allows a user to safely and easily share visual content of a computer screen at a particular time. As such, these applications provide an easy way to share complex information between users.

Frequently, however, participants desire to interact with portions of the slideshow which include interactive content (e.g., Uniform Resource Locator). For example, when a URL is presented within a slideshow, participants must manually copy the URL into a Web browser to view the content associated with the URL. That is, participants view a non-interactive image of the interactive content. These current manual approaches are time consuming and error prone. As such, collaborative applications limit the participant capability to interact with valuable information which can lead to significant frustration and a decreased participant experience.

BRIEF SUMMARY

One aspect of the present invention can include a system, a computer program product, an apparatus, and a method for dynamically enabling an interactive element within a non-interactive view of a screen sharing session. A non-interactive screen sharing session executing within a computing device can be identified. The device can be communicatively linked to different computing devices of the screen sharing session. The contents of the remote screen buffer can be analyzed to determine a graphical representation of a Uniform Resource Locator (URL) within the contents prior to presenting the contents of the buffer within the device. A visible information item can be extracted and a non-visible reference can be established from the representation. An area surrounding the representation including position and dimensions of the representation within the contents can be determined. The representation of the URL can be replaced with an interactive element in real-time. The element can include the visible and non-visible reference. The contents of the buffer can be presented within an interface associated with the session of the device, responsive to the replacing.

Another aspect of the present invention can include a computer program product, an apparatus, a method, and a system for dynamically enabling an interactive element within a non-interactive view of a screen sharing session. A collaboration engine can be configured to dynamically replace a graphical representation of URL within the contents of a screen buffer with a visible element and a non-visible element of an interactive element. The replacing can be performed prior to presenting the contents within an interface of a computing device in real-time during a screen sharing session. The interface can be a non-interactive interface presenting the screen buffer of the screen sharing session. A data store can be able to persist a resource mapping, a screen buffer, and/or a URL.

FIG. 1 is a schematic diagram illustrating a set of scenarios 110, 150 for dynamically enabling an interactive element within a non-interactive view of a screen sharing session in accordance with an embodiment of the inventive arrangements disclosed herein. In scenario 110, a sending device 111 and a receiving device 130 can be communicatively linked during a screen sharing session 112. When a Uniform Resource Locator (URL) 116 is presented within shared screen 114 of device 111, an interactive element corresponding to the URL 116 can be presented within non-interactive view 132 of device 130. That is, non-interactive view 132 can have selectively interactive portions. For example, session 112 can be a Web-based slideshow presentation with an interactive slide content such as an embedded video.

In scenario 110, a shared screen 114 can include one or more URLs 116 which can be interacted with by one or more users of device 111. For example, screen 114 can include a desktop screen with three visible applications, each presenting content such as source code text, a Web site URL, and an image. Screen 114 can be shared with device 130 within session 112 as non-interactive view 132. Non-interactive view 132 can include a screen buffer 136 which can include content 137. Content 137 can include a graphical rendering of screen 114. For example, content 137 can be an image of the screen 114 at the beginning of a session (e.g., initial screen capture). Content 137 can be continuously conveyed to device 130 responsive to screen 114 changes.

In scenario 150, a content 137 can be presented within a screen buffer 136 of device 130. During session 112, image analysis 140 can be continuously performed to obtain a graphical representation 152 within content 137. Representation 152 can be an image of a URL 116 such as a bitmap. Representation 152 can be determined utilizing traditional and/or proprietary pattern matching techniques. In one instance, representation 152 can be identified using regular expression matching during image analysis 140. In the instance, optical character recognition can determine specially formatted text strings (e.g., URIs) which can be matched against traditional and/or proprietary expressions. That is, the disclosure can be highly configurable enabling customized selection and/or identification of graphical representations of URIs.

Data extraction 152 can be performed to extract visible information and/or a non-visible reference of the representation 152. In one instance, extraction can determine visible and/or non-visible reference from optical character recognition. In the embodiment, when a URL is determined, the text and link information of the representation can be extracted to create an interactive element 160.

In one instance, element 160 can replace the graphical representation 152 within the buffer 136 during a dynamic substitution 154 action. In the instance, element 160 can be visually presented within the non-interactive view 132 instead of representation 152. For example, element 160 can be overlaid onto representation 152 within buffer 136 which can be presented during rendering content 137.

In one embodiment, element 160 can be associated with a resource mapping 138 to enable element 160 to function similar to a URL 116. In the embodiment, mapping 138 can be an index which can link an element 160 with an application 134 which can be executed to present and/or process resource 162.

In one embodiment, interactive element 160 can be a hyperlink which can be associated with a resource 162. In the embodiment, selection 156 of the element 160 can trigger the presentation of a resource 162 within an interface 140. For example, when a mouse click is registered within the interactive region of the hyperlink (e.g., element 160), a Web browser can present a Web site (e.g., resource 162).

It should be appreciated that URL 116 and/or representation 152 can include text content, video content, image content, audio content, and the like. It should be understood that element 160 can visually replicate representation 152 within view 132. That is, element 160 can appear visually similar to traditional interactive content such as images and/or video.

In one embodiment, the disclosure can be utilized to provide interactivity with embedded content within a screen sharing session. In one instance, the disclosure can be realized within a client side solution as described herein. In another instance, the disclosure can be embodied within a server side architecture (e.g., system 300, engine 320).

It should be appreciated that, session 112 can be initiated in a traditional and/or proprietary manner. For example, session 112 can be initiated from an email invitation for a Web conference. Session 112 can be associated with encryption, login authentication, access list mechanisms, expiration limitations, and the like.

It should be appreciated that the disclosure can be utilized to match visual patterns including, but not limited to, traditional chroma schemes, non-traditional schemes, and the like. For example, the disclosure can be configured to detect traditional Web browser links which can appear as a blue underlined portion of text.

In step 205, a screen sharing session can be established between a receiving device and a sending device. In step 210, a Uniform Resource Identifier (URL) can be presented within an interface of the sending device. For example, a URL of a Website can be presented within a navigation bar of a Web browser. In step 215, a screen buffer of the receiving device can be identified. The buffer can be identified utilizing traditional resource identification schemes. In step 220, the buffer can be analyzed to determine a graphical representation of the URL within the buffer. In step 225, if a graphical representation of the URL is found, the method can continue to step 235, else proceed to step 230. In step 230, an option to manually select the graphical representation can be presented. The manual option can include a traditional and/or proprietary selection tool such as a lasso, a rectangle selection tool (e.g., visible marquee), and the like.

In step 235, a graphical representation can be processed to extract visible information and a non-visible reference. In step 240, the area surrounding the graphical representation and position can be established. Step 240 can be performed utilizing feature detection, edge detection, and the like. In step 245, the area can be replaced with an interactive element within the screen buffer. In step 250, the screen buffer can be presented within an interface of the receiving device. In step 255, if the interactive element is selected the method can continue to step 260, else return to step 220. In step 260, one or more interface options can be optionally presented. Interface options can include, but are not limited to, copying the interactive element, copying element information, executing interactive element, setting element application association, and the like.
